Preview:


Adaptive immunity is faster to respond to threats and infections than the innate immune response

A. TRUE

B. FALSE

C. Sometimes true

D. Sometimes false


How do vaccines work?

A. They don’t

B. Vaccines use the body’s natural adaptive immune system to build up a resistance to a disease by creating antibodies before we are ever exposed to it giving us increased resistance or even complete immunity to the disease

C. vaccines give us the full disease, and your body will either fight it or not

D. I have no idea what a vaccine is


This system learns about different pathogens over time. It takes longer to respond and has specific responses for different types of pathogens

A. innate immune system

B. adaptive immune system


Widespread immunity that protects the population from the spread of disease is called

A. seropositivity

B. cross-reactivity

C. epidemic prophylaxis

D. herd immunity

The cross-linkage of antigens by antibodies is known as

A. TRUE

B. FALSE


During a secondary exposure to a pathogen the immune system will:

A. React slowly

B. Produce few antibodies due to fatigue from the first infection

C. React more quickly and produce a greater number of antibodies

D. Act the same as the primary exposure


This type of immunity can be called nonspecific and refers to the bodies defenses that are present since birth.

A. resistance

B. adaptive immunity

C. acquired immunity

D. innate immunity


The green circle represents a/an

A. vaccine

B. immune cell

C. antibody

D. antigen


This type of immunity is acquired during one’s lifetime. It is induced by antigens that invade the body.

A. innate immunity

B. adaptive immunity

C. nonspecific immunity

D. normal microbiota


Which type of immunity has memory?

A. innate

B. adaptive/acquired


Which of these scenarios could be a direct cause of a disease becoming a pandemic?

A. sick child attending school

B. sick family returning from a foreign country

C. mosquito in a field next to houses

D. patient sneezing on a doctor


What role do cytotoxic T cells play in immune response?

A. prevents immunization from occurring

B. binds to processed antigens and B cells

C. produces lysozymes to break down cell walls

D. destroy pathogens and release cytokines


The response to an infection. Causes the area to redden, swell, and feel warm.

A. Fever

B. Mucus

C. Dilation

D. Inflammation


A part of the innate immunity. The bodies defensive response caused by microbial infection, physical damage or chemical agents.

A. phagocytosis

B. edema

C. cytotoxicity

D. Inflammation


Since we have our immune system to protect us from disease, why do we still need a vaccine?

A. Because some diseases are too severe for our immune system.

B. Because adaptive immunity takes days to weeks to initiate a response and sometimes it is too late.

C. Because some people are immune deficient or have weak immune systems.

D. All of the above


Which type of cell actually secretes antibodies?

A. T cell

B. macrophage

C. plasma cell

D. monocyte


Which line of defense includes the skin, sweat, mucous membranes, and normal microbiota?

A. First

B. Second

C. Third


Why does the Adaptive Immune System keep a memory of the pathogens they fight off, but Innate System does not?

A. Adaptive immunity is present at birth and needs to keep a memory of these pathogens over time, but Innate immunity is temporary so it does not a memory of pathogens.

B. Adaptive immunity is short lived, it keeps a memory of pathogens for future reference, whereas Innate immunity is present at birth so it does not need to keep a memory.

C. Innate immunity does not fight off pathogens so it cannot keep a record, while Adaptive immunity only fights off pathogens, therefore needing to keep a memory of them.


Which of the following is NOT part of the first line of defense?

A. skin

B. B cells

C. sweat

D. lysozyme


Vaccines stimulate your body to produce _____________

A. viruses

B. antigens
